.Toa ll whom it may 05min.- Be it known that I, JAMES A.:MrToHELL, a citizen of the United States, resldmg at .iMcCrory, inithe county of Woodrufi and State of Arkansas, have invented certain new and useful Improvements in Water- Lifts,-of which the followingis aspecif cation, reference being had'to the accompanying drawings. Y

This invention relates to certain improvements :in water lifts and it is an object of the invention to provide a device of. this general character whereby -thejwater will be elevated under the influence of air pres sure. 7 Itis also an object of the inventionto providea novel and improved device of this general character wherein a controlling valve is employed and whereby said'valve may be unseated under air-pressure independently of the pressure employed in the elevation of the water, and whereby said pressure for arrangement of the several parts of my improved water lift whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood I will now. proceed to (18",

scribe the same withreference to the accompanying drawings, wherein is disclosed a view partly in section and partly in elevation of a water lift constructed in accordance with an embodiment of my invention.

As disclosed in the accompanying drawings, 1 denotes a tubular member of predetermined dimensions and adapted to be disposed within a source of water supply and for which reason the lower end portion thereof is pointed.

Adjacent its lower end the tubular member 1 is divided by the partition 2 while the portion of the walls of the'member below said partition 2 is perforate, as at 3, in order to'aflord the requisite ingress of water within said member. The upper end portion of to a suitable'source ofdischarger 5;

The opening5 is adapted to be closed by the icover 6.

-- As herein discl'osed,the source ofair supply comprises thetank T and inwhich' 'air is adapted to becompressed inany preferred The lower end of the is provided withm-af restricted extension '7 which is returned relative to the pipe 4 and'extends a predetermined distance above the partition W 2, the upper 'endportion of said extension 17 having interposed therein a check' valve-8 of any ordinary or preferred type. The extension 7 "is adapted to terminate 'below the water levelor line so that as the air is discharged through the extension 7, the water will be lifted or elevated as is believed I to be self-evident.

The partition 2 to one side of the pipe 4 is. provided with an opening 9 defined by a valve seat 10 and with which seat coacts terminates in an upturned portion 15 positioned substantially directly below the valve 11, and it will at once he self-evident that the air passing through said pipe l lwill serve to elevate the valve 11 and to prevent the accumulation of sand or other foreign substance upon the seat 10. I

Interposed in the pipe 14: and exterior of the member 1is a valve 16 herein disclosed as of a globe type and whereby the flow of the air under pressure through said pipe 14 is readily and conveniently controlled.

By having the pipes 4 and 1 1 engaged with the partition 2, it will be at once perceived that the same may be readily removed from within the member 1, although if prethought tO'kbG obvious that a water lift (con structed' in accordance "with 'iny' invention and facility With which it may be assembled,
